I've had 2 beers, how long before I can drive again?

Don't the laws apply to all vehicles???

 

I'd say about five years.

 

4 hours is the limit.


§392.5 Alcohol prohibition.
(a) No driver shall'
(a)(1) Use alcohol, as defined in §382.107 of this subchapter, or be under the influence of alcohol, within 4 hours before going on duty or operating, or having physical control of, a commercial motor vehicle; or

 

when you have none in your system. Their is no generic answer, just like "I only had 2 drinks". Your drink may be 12 oz and mine drink may be 22 oz. Each person's metabolism is different. Each person's body processes the booze differently. What may take me 3 hours , may take you 5 hours. It depends on how much food someone has consumes and if the alcohol readily is absorbed through the walls of your stomach or if it's soaked up by some sort of food in your belly and is absord at a slower rate. Way to many variables to give you any kind of answer. Best advice, don't drink at all in you plan to get in your rig and run a load. I personally have seen to many the last few months driving a tractor trailer who have been drinking.

 

Our company policy: 8 hrs from bottle to throttle.

 

I thought it was no alcohol at all in the 4 hours preceding coming on duty or the performance of any safety sensitive work provided that the driver's BAC was below 04.
